Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design, it being understood that the tread pattern repeats circumferentially throughout the outer circumference and shoulder of a tire, the opposite side perspective view being identical thereto; and

FIG. 2 is an enlarged fragmentary front elevation view of the tire tread thereof of FIG. 1; and,

FIG. 3 is a cross-sectional view taken along line 3—3 in FIG. 2.

In the drawings, the dark stippled surface shading represents the recessed groove portions of the tire tread with a groove depth as illustrated in FIG. 3. The broken line disclosure of the tire sidewall and inner bead is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
